What are some of the rules about the Internet that were taught to you but are now completely ignored?
For me, it was that the Internet never forgets and that you should never enter your real name. In my opinion, both of these rules are now completely ignored.
The same people who warned us about the dangers of the internet and not to believe everything, are now the ones readily falling for and spreading conspiracies and lies from social media.
I suspect now it was never about "don't believe everything", it's just been "believe what I believe". Which I suppose follows Nietzsche's thought on the transition from religion to ideology.
